Synthesis, Structures and Properties of Emission Nanomaterials Based on Lanthanide Oxides and Mix oxides

Nanomaterials based on lanthanide oxide (Ln2O3) and multielement Ln2O3 are become increasingly an important materials in development of breakthrough technology in optoelectronics and biomedicine area. A range of Ln2O3 such as Y2O3, Gd2O3, Tb3O4, Eu2O3, with the different nanoforms of particle, rod, wire and tube have been synthesized in using the soft template method. The growth mechanism to the nanostructures could be curiously affected by solution-solid process, anisotropic crystal in corporate with hydrogen bond interaction and polymers conformation. The transformation process from Y2O3-rod to tube forms has found and investigated to control the synthesis. The crystal structures, size, shape of the Ln2O3 products have determined by XRD, FESEM, and TEM. The luminescence properties of a variety of the synthesized nanophosphors Y2O3: Eu,Tb; YVO4: Eu; Tb(OH)3; TbPO4; EuPO4 have been investigated toward to develop a fluorescent label in biomedicine research.
